Can a CommandLine parameters for CCminer be used to select which video card to run on?
Thanks
You mean something like this? https://github.com/cbuchner1/ccminer/blob/master/README.txt
Devices (or GPU's) seem to be listed with --devices?
-d, --devices gives a comma separated list of CUDA device IDs
to operate on. Device IDs start counting from 0!
Alternatively give string names of your card like
gtx780ti or gt640#2 (matching 2nd gt640 in the PC).
I haven't tried it out myself, but i don't see why this wouldn't work.
Depending on what version you're using, there might be different/more commands. This one for example has some extra commands it seems.
